Vector Diagrams and Resultant forces

When we represent forces on a grid, how should we arrange them?


From tip-to-tail

When you draw 2 forces on a grid, how do you calculate the resultant force?


Measure the hypotenuse

If you were to draw out forces on a grid (more than 2) and they all fit together perfectly to make a triangle, what does that mean?


There is no resultant force, the object is in equilibrium

How do you measure the direction of a force, using a grid?


Measure the bearing
